For adjusting the length ofthe crayon the 110 The rear end of the barrel is also provided outercasing 12 is first removed, the tube 11 with external screw threads toreceive the and collar 3 are also removed from the outer end and thesleeve 9 may then be slipped off of the barrel 2, though this may not benecessary. The crayon within the barrel may be projected from the openend thereof by proper rotation of the rod 7 as described, after whichthe nut 3 is threaded upon the members 2 until the crayon is securelyclamped in the barrel. Nhen fresh crayon is inserted in the barrel 1, itis necessary to remove the cap 5 from the rear end thereof. The crayonis now placed within the barrel and is forced from the open end thereof,when the cap may be readjusted in position. The head 7 of the adjustingrod 7 is of course disposed in contact with the rear end of the crayonand the milled head 8 manipulated until the proper length of crayonprotrudes from the open end of the barrel. lVhen the first portionprojected is used up the adjusting rod is threaded inward to present afresh marking portion un til the crayon has been entirely consumed.

Thus it will be seen that I have provided a crayon holder wherein thechalk will be securely held in position when it is desired to use thesame, and may be rapidly adjusted in the tube or barrel so that the samemay be always ready for instant use. The parts comprising my improvedholder are very few and of extremely simple construction, which are veryquickly assembled or disassembled. The sleeve 9, cover 11, and outercasing 1:2 are all to be made of aluminum, whereby the device isrendered extremely light, so that the same may be quickly handled.

The nut 4, cap 5 and adjusting rod 7 are preferably constructed ofbrass, though it t will of course be understood that the same may beformed of any other material applicable to the purposes for which thesame are designed.

The barrel 1 would preferably be formed of sheet steel to secure theproper resiliency of the plates 2.

After the crayon has been properly adi justed from the end of thebarrel, the sleeve 9 and the outer casing 12 may be replaced to providea smooth surface by which the holder may be firmly grasped andmanipulated.

When the parts are assembled as shown in Fig. 1, the recesses 10 formedin the end of the barrel 9 receive the lugs 5 formed upon the cap 5, andwhen the casing 12 is removed for the purpose of adjusting the crayonfrom the end of the barrel, any rotative movement of the cap and barrelwill be prevented.

It will be understood that the crayon may be of any convenient size andthat the proportions of the various parts may be altered withoutmaterially effecting the construction or operation of the holder.

Having thus described my said invention, what I claim as new and desireto secure by United States Letters Patent is:

A holder of the character described comprising a hollow split barrel, aclamping nut adapted to have threaded engagement with one end of saidbarrel, a cap upon the other end of said barrel, lugs integrally formedwith said cap at diametrically opposite points, an adjusting rodthreaded through said cap, said rod having a plunger head upon its innerend, a. collar disposed upon said barrel, a cylindrical sleevesurrounding said barrel and extending between said cap and said collar,said sleeve having recesses formed in one end thereof adapted to receivethe lugs formed upon said cap, a tube provided with internal screwthreads adapted to be threaded upon the split end of said barrel, and acasing disposed over said barrel in threaded engagement with sleeve.

In testimony whereof I aiiiX my signature, in presence of two witnesses.
